"I was like, 'This is not a good look -- a bunch of drunk moms in the middle of the day,'" she continued. However, the real reason the police officer came over was to show the actress a tattoo on his arm.

"He was like, 'Oh no, I backed up because I wanted to show you that I have you on my arm!’" said Alba, who recorded the amazing coincidental encounter in a video she shared to Instagram.
